Answer 1

Answer:

see explanation

Step-by-step explanation:

Sum the sides of both polygons and equate.

(20)

x + 4 + x + 2 + x + 5 = 2(x + 1) + 2(x + 3) ← distribute parenthesis

3x + 11 = 2x + 2 + 2x + 6

3x + 11 = 4x + 8 ( subtract 3x from both sides )

11 = x + 8 ( subtract 8 from both sides )

3 = x

(21)

5(12x) = x + 7 + 6x + 9 + x + 10

60x = 8x + 26 ( subtract 8x from both sides )

52x = 26 ( divide both sides by 52 )

x = $\frac{26}{52}$ = $\frac{1}{2}$
